Run 3 grades of warnings of leakage accident
Economize on electricity control implementation process:
If actual pressure of supply water will obtain positive pressure differential less than setting pressure, control system, this difference is through meter
Calculate and change, calculate the value added of converter output frequency, the value is exactly to reduce actual pressure of supply water with setting pressure
Difference, the current output valve of this increment and converter is added, the value for drawing is the frequency that converter currently should be exported
Rate.The frequency increases water pump assembly rotating speed, so that actual pressure of supply water is improved, the process will be weighed in running
It is multiple, till actual pressure of supply water and setting pressure are equal.If actual pressure of supply water is higher than setting pressure in running,
Just conversely, the output frequency of converter will be reduced, the rotating speed of water pump assembly reduces situation, and therefore actual pressure of supply water subtracts
It is little.Equally, the result for finally adjusting is that actual pressure of supply water and setting pressure are equal.
(1) when system starts to start, hydraulic pressure is 0, and converter is dragged to No. 1 starting of pump station, constant pressure economize on electricity control terminal inspection
Measure mouth of a river pressure and input control system compares with setup pressure value, converter is controlled by intelligent controller and drags water pump electricity
Machine raises speed, and when equal with setup pressure value, locks frequency converter frequency, and motor speed keeps constant.When water consumption change causes
When hydraulic pressure increases or reduces, due to the adjustment effect of closed loop, converter output frequency is reduced or raised, and is dragged pump motor and is slowed down
Or Accelerating running, balance with setting value until reaching hydraulic pressure again.
(2) increase hydraulic pressure in user's water consumption to rise, water consumption cannot be also met when converter reaches upper frequency limit,
I.e. hydraulic pressure detected value is also less than hydraulic pressure setting value, hydraulic pressure closed loop feedback link is at this moment cut off, by Phase-Locked Synchronous Absent measures water pump
From frequency conversion to the switching of power frequency, when reaching both frequencies and being equal, switch, simultaneity factor sends control command, and system is extensive
The multiple closed loop feedback control to hydraulic pressure, converter drags No. 2 water pumps with soft starting mode operation, until water system hydraulic pressure recovers
To setting value；
(3) if accumulative water consumption continues to increase, when the water pump in converting operation state reaches upper frequency limit again,
System occurs as above to switch again, until system reaches new balance；It is possible to last water pump occur in water use peak
Put into converting operation and reach upper frequency limit, be not met by user's water consumption, hydraulic pressure value is less than setting value, now control system
System output alarm signal reminds staff's relevant issues.
(4) persistently reduce hydraulic pressure in water consumption to raise, in the presence of closed loop control, if converter drags water pump operation
When frequency be less than lower limit, hydraulic pressure also high pressure set point, at this moment system send instruction close power frequency operation the 3rd water pump,
System continues to realize that the closed loop feedback to hydraulic pressure is adjusted by variable frequency pump, so that hydraulic pressure recovers constant reaches setting value；Work as water consumption
Continue for reducing, when actual hydraulic pressure value is less than default hydraulic pressure value, and under at this moment converter output frequency has had been reduced to
Limit frequency, now will occur as above to switch, till only a remaining variable frequency pump runs；When water consumption is at a low ebb, have
It is likely to occur only one frequency conversion pump operation and in lower-frequency limit position, now according to this low ebb time length and water can be used
Feature, can make system be transformed into intermittent water or low capacity water pump operation state.
From the above, it is seen that this utility model is simple to operate and with short circuit, overload, overheated, excessively stream, overvoltage, event
The strong defencive functions such as barrier memory, accident judgement and display.Electricity-saving control device composition includes control terminal, signal converting
Device, ammeter, effusion meter, remote pressure collection etc..It is intrinsic by this ground pressure, flow, remote pressure study calculating pipe network first
Pipe damages parameter, completes self study and Jing after being successfully tested, dismountable remote pressure collecting device.This ground pressure, flow, pipe are damaged
Parameter substitutes into mathematical model, calculates feedback control parameters, controls converting operation.Change with actual used water, real-time adjustment control
Feedback parameter, while making remote pressure stable, reaches economize on electricity purpose.The scientific management of effectively solving agriculture drinking-water, at utmost
Saves energy and water resource are reached, economic and social benefit is notable.
